Embodiment 1

[0027]A kind of special organic soil for raising vegetable seedlings, its raw material formula components are as follows: 4 parts of aged Agaricus bisporus grass-soil mixture, 2.5 parts of mixed organic materials of vinegar dregs and cassava dregs after composting fermentation treatment, 1.5 parts of coconut peat, river 1.5 parts of pond mud or frozen soil or humus soil, 1.5 parts of carbonized rice bran, 0.75 parts of vermiculite, and 0.75 parts of perlite; in addition, add 0.2% of the total weight of 15-15-15 NPK ternary compound fertilizer. Among them, the aged Agaricus bisporus grass-soil mixture is a mushroom culture medium with rice and wheat straw as the main raw material. The waste materials left after the growth of mushroom hyphae to produce mushrooms are naturally stacked for more than one year and fully decomposed, and then dried in the sun. The brown Agaricus bisporus grass soil mixed with organic materials obtained after drying and mechanical crushing, the grass so...

[0031] A kind of special organic soil for vegetable seedling raising, its raw material formula components are as follows: 3 parts of aged Agaricus bisporus grass-soil mixture, 2 parts of mixed organic materials of vinegar dregs and cassava dregs after composting fermentation treatment, 1 part of coconut bran, river 1 part of pond mud or frozen soil or humus soil, 1 part of carbonized rice bran, 0.5 part of vermiculite, 0.5 part of perlite; in addition, add 0.1% of the total weight of 15-15-15 NPK ternary compound fertilizer. The physical and chemical indicators of the organic soil are: N+P 2 o 5 +K 2 O The total nutrient content is 2.5%, the organic matter content is 20%, the water content is 50%, the total porosity is 65%, and the bulk density is 0.2g / cm 3 , the air-water ratio is 1:4, the EC value is 2-2.5mS / cm, the pH is 5.8, and the particle size is 0-5mm, of which 2-4mm accounts for 50-60%.

[0032] Among them, the composting fermentation treatment is in the sunshine b...

Embodiment 3

[0037] A special organic soil for vegetable seedlings. The volume ratio of the organic soil formula is: 5 parts of aged Agaricus bisporus grass-soil mixture, 3 parts of mixed organic materials of vinegar residue and cassava residue after composting and fermentation treatment, 2 parts of coconut bran, and river pond 2 parts of mud or frozen soil or humus soil, 2 parts of carbonized rice bran, 1 part of vermiculite, and 1 part of perlite; in addition, add 0.3% of the total weight of 15-15-15 NPK ternary compound fertilizer. The physical and chemical indicators of the organic soil are: N+P 2 o 5 +K 2 The total nutrient content of O is 3.5%, the organic matter content is 26%, the water content is 35%, the total porosity is 75%, and the bulk density is 0.8g / cm 3 , the air-water ratio is 1:2, the EC value is 1.2-2.0mS / cm, the pH is 7.0, and the particle size is 1-5mm, of which 2-4mm accounts for 50-60%.

Abstract

The invention discloses a special organic soil for vegetable seedling culture and belongs to the technical field of soilless culture. The raw material formula of the organic soil contains the following ingredients in parts by volume: 3-5 parts of aged agaricus bisporus sward mixture, 2-3 parts of mixed organic material of vinegar residue and cassava residue which are subjected to composting and fermenting, 1-2 parts of coco coir, 1-2 parts of river/pond sludge or frozen soil or humus soil, 1-2 parts of plant ash, 0.5-1 part of vermiculite and 0.5-1 part of pearlite; in addition, a ternary compound fertilizer, of which the weight is 0.1-0.3% of the total weight, is added; according to the organic soil, the content of total nutrients is 2.5-3.5%, the content of organic matters is not lower than 20%, the moisture content is 35-50%, the total porosity is 65-75%, the volume weight is 0.2-0.8g/cm<3>, the gas-water ratio is 1:(2-4), the EC value is not greater than 2.5sM/cm, the pH is 5.8-7.0, the grain size is not greater than 5mm, and granules with the grain size of 2-4mm account for 50-60%. The organic soil is granular solid of which the appearance is dark-brown or black-brown, and is odorless. The special organic soil for the vegetable seedling culture, disclosed by the invention, is loose in texture and high in nutrient, does not float during watering and is applicable to the majority of vegetable plug seedling culture.

Description

technical field [0001] The invention relates to a nutrient soil for soilless cultivation of vegetables, in particular to a special organic soil for raising vegetable seedlings, and belongs to the technical field of soilless cultivation of vegetables. Background technique [0002] Soilless cultivation refers to the method of irrigating with substrate or nutrient solution without using natural soil. It is mainly used in the cultivation of vegetables and other crops. It is a high-yield and high-quality advanced technology that saves water, fertilizer and labor. In the middle of the 19th century, it began to be used in agricultural production in the 1930s. It was widely used in the Netherlands, Japan, New Zealand, Italy and other countries. At present, soilless cultivation technology has been applied and developed in more than 100 countries around the world. [0003] The research and application of soilless cultivation technology in my country started relatively late, but the re...
